Narrated Aisha:

I used to stretch my legs towards the Qibla of the Prophet while he was praying;
whenever he prostrated he touched me, and I would withdraw my legs, and whenever he stood up, I would restretch my legs.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا مَالِكٌ، عَنْ أَبِي النَّضْرِ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كُنْتُ أَمُدُّ رِجْلِي فِي قِبْلَةِ النَّبِيِّ ﷺ وَهُوَ يُصَلِّي، فَإِذَا سَجَدَ غَمَزَنِي فَرَفَعْتُهَا، فَإِذَا قَامَ مَدَدْتُهَا.
